Why Windows struggles with HEIC
HEIC photos are compressed with HEVC (H.265). HEVC is covered by patents, and licensing it costs money, so Microsoft doesn't include full support in every copy of Windows. Instead, support comes as add-ons from the Microsoft Store.
The result is that the same HEIC photo might open on one Windows PC and show "This file format is not supported" on another, depending on what's installed.

Option 1: Install the Microsoft extensions
This teaches Windows itself to read HEIC, so Photos, File Explorer thumbnails and some other apps can open the files.
- Open the Microsoft Store app.
- Search for HEIF Image Extensions and install it. It's free. On many Windows 11 PCs it's already installed.
- Search for HEVC Video Extensions and install it. This is usually a small paid add-on, and HEIC photos generally need it because the image data is HEVC.
- Restart the Photos app, or your PC if thumbnails don't appear.
- Double-click a HEIC file. It should open in Photos.
A few caveats:
- Not every app uses the Windows codecs. Some photo editors, upload tools and older software still won't open HEIC.
- The extensions only help on that one PC. Anyone you send the files to needs the same setup.
- Microsoft occasionally renames or repackages these extensions, so the Store listing may look slightly different.
Windows 10 vs Windows 11
The process is the same on both. The main difference tends to be what's preinstalled. Windows 11 machines more often ship with HEIF Image Extensions already present, and some PC makers include HEVC support too. On Windows 10 you're more likely to need both installs. If HEIC opens fine already, you don't need to do anything.
Option 2: Convert HEIC to JPG
Converting gives you files that open in every Windows app, every website and every email client, with no extensions anywhere.
- Open the converter on this page in any modern browser.
- Drag your HEIC files, or a whole folder, onto the drop zone.
- Leave the default settings, or switch colour to sRGB if you'll use older Windows software that shows iPhone colours a bit dull.
- Click Download all to get a ZIP, then extract it in File Explorer.
Because the conversion runs in your browser, nothing is uploaded. After your first visit it even works without an internet connection. If you have hundreds of files, the batch HEIC converter adds pause, resume and retry.
Option 3: Make your iPhone send JPGs
If your HEIC files arrive by USB cable, you can fix this at the source.
- On your iPhone, open Settings.
- Tap Photos.
- Scroll to Transfer to Mac or PC and choose Automatic.
- Reconnect the iPhone and import again, using the Windows Photos app or File Explorer.
With Automatic, the iPhone converts photos to a compatible format such as JPG as they're copied. With Keep Originals, you get HEIC files. Note that this only affects cable transfers. Photos that reach your PC through iCloud, AirDrop to another device, or cloud drives may still be HEIC.
To stop the iPhone creating HEIC files at all, see our iPhone camera settings guide. It covers the storage trade-off too.
Option 4: Use a cloud or web viewer
If you just need to look at a photo:
- OneDrive on the web generally shows previews of HEIC photos uploaded from an iPhone.
- Google Photos displays HEIC files in the browser.
- iCloud Photos at icloud.com shows your library, and lets you download photos, with options that vary by browser.
These are fine for viewing, but downloading may still give you a HEIC. And uploading private photos to a cloud service is a bigger step than viewing them locally. For a quick look without uploading anything, the HEIC viewer opens files right in your browser.
Troubleshooting
The HEVC part is usually missing. Install HEVC Video Extensions as well as HEIF Image Extensions, then restart Photos.
Thumbnails are blank in File Explorer
Restart Windows Explorer (Task Manager → Windows Explorer → Restart) or reboot. If thumbnails still don't show, the extensions may not be installed for your account.
The photo opens but colours look washed out
Some Windows apps ignore the Display P3 colour profile iPhones use. Convert with the sRGB option on to bake the colours in for older software.
A specific app still refuses HEIC
Plenty of programs don't use the Windows codecs at all. Convert to JPG or PNG. For Adobe software, there's a dedicated HEIC for Photoshop preset.
Which should you choose?
If you live in a mixed iPhone and Windows household and look at photos daily, install the extensions and set the iPhone to Automatic for transfers. If you only hit HEIC now and then, convert the files you need and move on. Still stuck? Our HEIC troubleshooting guide covers more situations.
